Besides, if the design of the 1917 was so great, why did the British not use the million or so 1914 rifles that Remington, Winchester and Eddystone sold them? I have never seen a picture of a WW1 British soldier holding one, much less evidence of their general use in the trenches.
In the winter of 1914-15 the British War Office was hard put to it to find rifles for the newly recruited armies, and under pressure from certain members of the Cabinet order for British caliber rifles were placed with the Winchester and Remington firms of America, which were ultimately increased to no less than 3.5 million rifles. In their enthusiasm, the contractors promised that deliveries would commence in the autumn of 1915, and set to work to build factories and housing accommodation for the large staff needed to cope with the colossal orders. But, alas, like so many other contractors, they failed in their promises, and deliveries in bulk did not start until the winter of 1916. Fortunately for the British troops, the wastage of rifles in trench warfare proved negligible, and the Kitchener armies were finally equipped, after some delay from the output of two British factories. By Christmas, 1916, however the American rifles were arriving in large numbers, and in February, 1917, the American factories were probably producing more rifles per week than any factories had ever turned out in the world’s history. As, however, the rifles were slightly different in type, though of the same bore as the British Service rifle, they were not sent to France, but were issued by our War Office to home defense troops, stations overseas, etc.
The British signed contracts, for what ever reasons, did not cancel them, by the time sufficient P14’s came out, they had enough Lee Enfields. Unlike the American Army, they decided not to have two service rifles with two logistic trains in their primary theater of operations, and used the P14 in a secondary role.
